Together, these three races make up the storied Triple Crown of Thoroughbred Horse Racing, and only 13 horses have every completed the impressive trifecta. The best betting sites have hundreds of straight and exotic bets for these major races, as well as Triple Crown futures where you can bet on winners weeks or months ahead of time for truly massive payouts.
